一.使用DOM生成和读取XML文件
实例一：
复制代码 代码如下:
<?php
//Creates XML string and XML document using the DOM
$dom = new DomDocument('1.0');
//add root - <books>
$books = $dom->appendChild($dom->createElement_x_x ('books'));
//add <book> element to <books>
$book = $books->appendChild($dom->createElement_x_x ('book'));
//add <title> element to <book>
$title = $book->appendChild($dom->createElement_x_x ('title'));
//add <title> text node element to <title>
$title->appendChild($dom->createTextNode('Great American Novel'));
//generate xml
$dom->formatOutput = true; // set the formatOutput attribute of domDocument to true
//save XML as string or file
$test1 = $dom->saveXML(); // put string in test1
$dom -> save('test1.xml'); // save as file
?>
实例二：
复制代码 代码如下:
$aa = "111";
$xmlstr = <<<XML
<?xml version='1.0'?>
<document>
<title>{$aa}</title>
<from>Joe</from>
<to>Jane</to>
<body>
I know that's the answer -- but what's the question?
</body>
</document>
XML;
$dom = new domDocument;
$dom->loadXML($xmlstr);
$test1 = $dom->saveXML();
$dom->save('test1.xml');
实例三：
test1.xml:
复制代码 代码如下:
<?xml version="1.0"?>
<books>
<book>
<author>Jack Herrington</author>
<title>PHP Hacks</title>
<publisher>O'Reilly</publisher>
</book>
<book>
<author>Jack Herrington</author>
<title>Podcasting Hacks</title>
<publisher>O'Reilly</publisher>
</book>
</books>
example.php:
复制代码 代码如下:
$doc = new DOMDocument();
$doc->load('test1.xml');
$books = $doc->getElementsByTagName("book");
foreach($books as $book){
$authors = $book->getElementsByTagName("author");
$author = $authors->item(0)->nodeValue;
$publishers = $book->getElementsByTagName( "publisher" );
$publisher = $publishers->item(0)->nodeValue;
$titles = $book->getElementsByTagName( "title" );
$title = $titles->item(0)->nodeValue;
echo "$title - $author - $publisher\n";
}
二.使用simple生成和读取xml文件
实例一：
复制代码 代码如下:
<?
$xmlstr = <<<XML
<?xml version='1.0' standalone='yes'?>
<books>
<book>
<title>Great American Novel</title>
<characters>
<character>
<name>Cliff</name>
<desc>really great guy</desc>
</character>
<character>
<name>Lovely Woman</name>
<desc>matchless beauty</desc>
</character>
<character>
<name>Loyal Dog</name>
<desc>sleepy</desc>
</character>
</characters>
<plot>
Cliff meets Lovely Woman. Loyal Dog sleeps, but wakes up to bark
at mailman.
</plot>
<success type='bestseller'>4</success>
<success type='bookclubs'>9</success>
</book>
</books>
XML;
//提取节点内容
$xml = new SimpleXMLElement($xmlstr);
foreach ($xml->book[0]->success as $success) {
switch((string) $success['type']) { // Get attributes as element indices
case 'bestseller':
echo $success. ' months on bestseller list<br>';
break;
case 'bookclubs':
echo $success. ' bookclub listings';
break;
}
}
//修改文本节点内容
$xml = new SimpleXMLElement($xmlstr);
$xml->book[0]->characters->character[0]->name = 'Big Cliff';
echo $xml->asXML();
//添加子元素的文本节点
$xml = new SimpleXMLElement($xmlstr);
$character = $xml->book[0]->characters->addChild('character');
$character->addChild('name', 'Yellow Cat');
$character->addChild('desc', 'aloof');
$success = $xml->book[0]->addChild('success', '2');
$success->addAttribute('type', 'reprints');
echo $xml->asXML();
?>
实例二：
复制代码 代码如下:
if (file_exists('test1.xml')) { //读取xml文件
$xml = simplexml_load_file('test1.xml');
var_dump(xml);
} else {
exit('Failed to open test1.xml.');
}
三.DOM和simple互操作
DOM导入simpleXML：
复制代码 代码如下:
<?php
$sxe = simplexml_load_string('<books><book><title>Great American
Novel</title></book></books>');
if ($sxe === false) {
echo 'Error while parsing the document';
exit;
}
$dom_sxe = dom_import_simplexml($sxe);
if (!$dom_sxe) {
echo 'Error while converting XML';
exit;
}
$dom = new DOMDocument('1.0');
$dom_sxe = $dom->importNode($dom_sxe, true);
$dom_sxe = $dom->appendChild($dom_sxe);
$test2 = $dom->saveXML(); // put string in test2
$dom -> save('test2.xml'); // save as file
?>
simpleXML导入DOM：
复制代码 代码如下:
<?php
$dom = new domDocument;
$dom->loadXML('<books><book><title>Great American
Novel</title></book></books>');
if (!$dom) {
echo 'Error while parsing the document';
exit;
}
$s = simplexml_import_dom($dom);
echo $s->book[0]->title; // Great American Novel
?>
实例一：
复制代码 代码如下:
<?php
//Creates XML string and XML document using the DOM
$dom = new DomDocument('1.0');
//add root - <books>
$books = $dom->appendChild($dom->createElement_x_x ('books'));
//add <book> element to <books>
$book = $books->appendChild($dom->createElement_x_x ('book'));
//add <title> element to <book>
$title = $book->appendChild($dom->createElement_x_x ('title'));
//add <title> text node element to <title>
$title->appendChild($dom->createTextNode('Great American Novel'));
//generate xml
$dom->formatOutput = true; // set the formatOutput attribute of domDocument to true
//save XML as string or file
$test1 = $dom->saveXML(); // put string in test1
$dom -> save('test1.xml'); // save as file
?>
实例二：
复制代码 代码如下:
$aa = "111";
$xmlstr = <<<XML
<?xml version='1.0'?>
<document>
<title>{$aa}</title>
<from>Joe</from>
<to>Jane</to>
<body>
I know that's the answer -- but what's the question?
</body>
</document>
XML;
$dom = new domDocument;
$dom->loadXML($xmlstr);
$test1 = $dom->saveXML();
$dom->save('test1.xml');
实例三：

<publisher>O'Reilly</publisher>
</book>
<book>

</book>
</books>

复制代码 代码如下:
$doc = new DOMDocument();
$doc->load('test1.xml');
$books = $doc->getElementsByTagName("book");
foreach($books as $book){
$authors = $book->getElementsByTagName("author");
$author = $authors->item(0)->nodeValue;
$publishers = $book->getElementsByTagName( "publisher" );
$publisher = $publishers->item(0)->nodeValue;
$titles = $book->getElementsByTagName( "title" );
$title = $titles->item(0)->nodeValue;
echo "$title - $author - $publisher\n";

$xml->book[0]->characters->character[0]->name = 'Big Cliff';
echo $xml->asXML();
//添加子元素的文本节点
$xml = new SimpleXMLElement($xmlstr);
$character = $xml->book[0]->characters->addChild('character');
$character->addChild('name', 'Yellow Cat');
$character->addChild('desc', 'aloof');
$success = $xml->book[0]->addChild('success', '2');
$success->addAttribute('type', 'reprints');
echo $xml->asXML();

一口气升级7个大模型SaaS应用，百度智能云：突出一个“开箱即用” - 2024/11/26
这一波大模型产业落地浪潮里，不少企业其实处在 “干瞪眼“的状态。
一种情况是，很多大模型产品看得见却摸不着，在台上一个个遥遥领先——今天Sora技精四座，明天英伟达的机器人又赢得满堂彩，可是到了台下一问：啥时候能用上啊？答曰：遥遥无期。
另一种情况是，企业想用上大模型，却又难免瞻前顾后——既要考虑场景融合，又得兼顾安全性，还要考虑打通现有系统，再加上各种部署成本和繁琐的采购流程……最后只能拂袖：罢了，再等等吧。

稳了！魔兽国服回归的3条重磅消息！官宣时间再确认！
昨天有一位朋友在大神群里分享，自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址，com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后，确实是网易的网址，也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情，因为以前都没有出现这样的情况，现在突然提示跳转到国服战网的网址，是不是说明了简体中文客户端已经开始进行更新了呢？
